Recent writing on the idea of a form of life has tended to be critical of the use made of this notion by writers such as Peter Winch, D. Z. Phillips and Norman Malcolm. Rightly or wrongly these writers have been regarded as meaning by ‘a form of life’, something like ‘a way or style of life’, and recent explicatory work on the notion has largely tended to discount this as a plausible interpretation of what Wittgenstein meant in his use of the expression. The intention of this paper is not that of direct intervention in this particular dispute, though the conclusions drawn, if correct, would have some bearing on it. The intention is rather to develop, in order to make use of it, the idea of a form of life within the context of a number of philosophical difficulties. I should certainly claim to be drawing upon the remarks made by Wittgenstein in his own use of the expression: but I should not claim to be expounding Wittgenstein. Hence I do not wish to enter into the disputes referred to above about what precisely Wittgenstein meant by the expression, though again, what I say, if not wholly misguided, should have some bearing on these disputes.
